COMBINED BURGLAR-ALARM AND CALL-BELL SPECIFIGA'I'IONforming part ofLetters Patent No. 568,532, dated September 29, 1896.

Application filed October 26, 1895. Serial No. 567,018. (No model.)

To all whom it may concern.-

Be it known that I, ISAIAH L. HAUsER, residing at Chicago, in the countyof Cook and State of Illinois, have invented a certain new and usefulImprovement in a Combined Burglar-Alarm and Call-Bell, of. which thefollowing, when taken in connection with the drawings accompanying andforming a part hereof, is a full and complete description sufficient toenable those skilled in the art to make, understand, and use the same.

This invention relates to the class of combined burglar-alarm andcall-bells wherein the position of the case or shell thereof relative tothe object or thing on which it rests determines whether or not the bellshall ring and an alarm or call be given; and the object of thisinvention is to obtaina combined alarm and call bell wherein, whenproperly wound, an alarm or call will be given if the device be raisedfrom its support or overturned thereon.

The preferred manner in which I obtain the objects sought by me is wellillustrated in the drawings referred to as forming a part of thisspecification, in which Figure 1 is an elevation of a combinedburglar-alarm and call-bell embodying my invention set or placed on asupport in position so that an alarm or call will not be given so longas it rests in such position on such support; Fig. 2, an elevation ofsuch combined burglar-alarm and call-bell in the position itautomatically assumes when overturned from the position thereofillustrated in Fig.1,in which position a burglar alarm or call is given;Fig. 3, avertical sectional view of the combined burglar-alarm andcall-bell; Fig. 4., a horizontal sectional view on line 4 4 of Fig. 3,viewed in the direction indicated by the arrows; Fig. 5, a bottom planView of the combined winding handle and disk forming the base on whichthe device automatically settles to rest when overturned from theposition thereof illustrated in Fig. 1, and Fig. 6 a perspective View ofsuch combined winding handle and disk. Fig. 7 is a vertical sectionalview of a portion of the machine and of a modification of the combinedwinding handle and disk, and Fig. 8a perspective View of such modifiedconstruction of the winding handle and disk.

A reference-letter applied to a given part is used to designate suchpart throughout the several figures of the drawings wherever the sameappears.

A A are the two parts forming the case of the machine.

B is the winding handle and disk, and B the stop-disk. Disks B B arearranged to constitute rests or bases,on one or the other of which themachine rests when placed on any support. hen the machine is resting ondisk B, (the clockwork hereinafter described being wound to an operativecondition,) an alarm or call will be automatically given; but when sucha machine is resting on disk B no alarm or call will be given, even ifthe clockwork referred to be wound to an operative condition. PartA ofthe case is weighted, as at a, so that when the machine is forced offthe part or disk B, as illustrated in Fig. 1, it will automaticallyoverturn and assume the position illustrated in Figs. 2 and 3, that is,resting on base 13.

The particular shape given the case A A is so given in view of theautomatic assuming by the machine of the position described on base B,such shape being necessary to insure the operation of the device as aburglar-alarm.

The part A of the case is made of bellmetal and constitutes a bell aswell as a part of the case.

C is a bell-hammer actuable by train or clockwork D when spring E of thetrain is wound and the stop mechanism controlled by stop-disk B is outof engagement with such train or clockwork.

I prefer to construct a train or clockwork and bell-hammer independentof the part A of the case and to secure it in such part A in the mannerillustrated in the drawings, although such construction is notanecessary part of my invention. In such construction F F are theplates, forming, in combination with posts f f f,t'he frame of the trainand bell-hammer.

G is the main or spring shaft, to which one engagement with detent-armN.

end of spring E is secured, the other end of the spring being secured tothe frame of the train in the ordinary manner.

11 is the main driving-wheel of the train, placed loosely on the shaftG, and h is the ordinary ratchet connection between the driving-wheel IIand the shaft G thereof.

I is a rotatably-mounted shaft having pinion J thereon, such pinionengaging with the wheel H and wheel K engaging with escapement L.Escapement L is secured 011 rockshaft M, to which rock-shaft the hammerC is secured by the wire 0. To this rock-shaft M there is also securedthe wire N, such wire N formingapart of the stop mechanism of themachine hereinafter called a detent-arm. The connection between wire Nof the stop mechanism and stop-disk B is obtained by mounting suchstop-disk B on the non-rota table but longitudinally-movable shaft b,extending pin 1) through such shaft 19, so that such pin forms a lugwhich, when the shaft 1) is in one'of its longitudinally possiblepositions, as indicated by dotted lines in Fig. 3, will engage withdetent-arm N and lock the train, and when in the other of its positionswill be out of engagement with such detentarm N and the train D unlockedor released.

0 is a spring yieldingly holding shaft 1) in position, so that lug b isnot in engagement with detent-arm N. Spring 0 is not sufficiently strongto sustain the weight of the machine. Hence when such machine rests onstop-disk B on support X, Fig. 1, the shaft 1) is forced longitudinallyin against the resistanee of spring 0 and lug b is brought into When themachine is lifted from the support X or overturned thereon, spring 0forces the shaft Z1 longitudinally into position, so that lug I) is outof engagement with detent-arin N and the train D is released and (thespring of the train being wound into an operative condition) sounds analarm and call.

The winding handle and disk B are secured 011 extension 9 of shaft G.

B 13 are serrations on the disk 13.

P is a string or cord secured to part A of the case of the machine, bymeans of which such machine can be attached to any desired object.

The modification illustrated in Figs. 7 and 8 consists in thesubstitution of winding-handles 13 on shaft G for the winding handle anddisk B hereinbefore described and the making of recess A in part A ofthe case of the machine, so that such handle B is contained therein whenturned into the position thereof illustrated in Fig. 7, and when soturned the machine will rest on the base a of such part A instead of 011the disk B, (the machine being overturned on its support.)

Q Q are screws by means of which the train D is attached to part A ofthe case.

The operation and manner of use of the combined burglar-alarm andcall-bell are: The spring is wound by the turning of handle and disk B,(on handle B and the machine is placed on support X so as to rest onstop-disk B. String P may be secured to any article or thing so thatmovement of such article or thing relative to the machine will overturnsuch machine, or the machine may be placed in position to be overturnedby the opening of a door or window or other thing. lVhen properlyresting on stop-disk B, the movement of the article or thing, or door,or window, will overturn the machine, and as soon as the weight thereofis off of the stopdisk B spring 0 will force shaft 1) longitudinallyoutward, disengaging lug I) from stop detent-arm N and an alarm or callwill be given. To use it as a call-bell, it is simply necessary to windthe spring of the train and rest the machine on the stop-disk B. lVhen acall is to be made, the machine is raised from off its support, when thebell will ring until replaced in position on its support and onstop-disk B.

The serrations B B tend to cause disk B to remain stationary, and thusshell or case A A will rotate on and around the shaft G while an alarmis being sounded.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination of atwo-part case, one part thereof having a weightedbase and the other part consisting of a bell and such case having aclock-train secured in the weighted part of the case, of alongitudinally movablc shaft extending through, and beyond the bell partof the case, a disk on which the machine can be rested on the outer endof the longitudinally-movableshaft, a spring yieldingly holding theshaft extended beyond the case and so that the detent-arm of the trainis out of engagement with a lug on the inner end of thelongitudinally-movable shaft, such lug arranged to engage with thedetent-arm and lock the train when the shaft is forced in from itsextended position, such spring not being of suiiicient tension to holdthe shaft extended when the weight of the machine is on the disk;substantially as described.

2. The combination of a two-part case, one part thereof having aweighted base and the other part consisting of a bell, with a clocktrainand a hammer actuated by the train in the weighted part of the case, anda longitudinally-movable shaft extending through the bell part of thecase, a disk on the shaft, stop mechanism between the movable shaft andthe clock-train, means for yieldingly holding the longitudinally-movableshaft in an extended position with the stop mechanism out of engagement,and means for antomatically forcing such shaft into position, with thestop mechanism in engagement, by the weight of the machine;substantially as described.

3. The combination of a clock-train, abell, a hammer actuable by thetrain, a lug yieldingly held out of engagement with the train by beingmounted on the inner end of a longitudinally-movable shaft the outer endof such shaft extending through and beyond the bell part of the case,and a spring holding the shaft yieldingly in an extended position, adisk on the outer end of the longitudinallymovable-shaft on which diskthe machine can be placed, and the lug thereby forced into engagementwith the train by the weight of the machine, and means for winding theclocktrain spring; substantially as described.

4. The combination of a two-part case, one part thereof having aweighted base and the other part consisting of a bell with a clocktrainthe shaft of the spring whereof extends through the weighted part of thecase, a disk on the end of the shaft, on which disk the machineautomatically settles to rest when overturned, a bell, a hammer actuatedby the train, a lug on a longitudinally movable shaft yieldinglyheld inan extended position so that such lug is out of engagement with thetrain, a disk on the outer end of the longitudinally-movable shaft onwhich disk the machine can be rested and such lug thereby forced intoengagement with the train until such machine shall have been overturnedfrom such position on the disk of the longitudinally-movable shaft orraised from off its support; substantially as described.
